Data.List.Key

Description

Variant of Data.List functions like group, sort
where the comparison is performed on a key computed from the list elements.
In principle these functions could be replaced by e.g. sortBy (compare on f),
but f will be re-computed for every comparison.
If the evaluation of f is expensive,
our functions are better, since they buffer the results of f.
